After winning the toss, South Africa made a positive start with the bat. An opening stand of 62 between Sune Luus and Tazmin Brits set the tone, giving the visitors early control. Brits led the way with a steady 53 from 49 balls, while captain Laura Wolvaardt anchored the innings with an unbeaten 41 off 33 deliveries.
Although the middle order faltered briefly, Kayla Reyneke changed the momentum with a powerful late cameo. The 20-year-old struck 28 runs from just nine balls, lifting South Africa to a competitive total of 177 for 5.
Reyneke, who was named player of the match, said afterwards: "Batting with Wolvaardt was a dream come true. I am just happy to get a win for the team."
In response, New Zealand started well in the PowerPlay, reaching 49 without loss. However, South Africa's bowlers quickly regained control once the field spread. Amelia Kerr provided resistance with a quick 32 off 18 balls, sharing a 39-run stand with Sophie Devine, but the hosts struggled to build lasting partnerships.
Ayabonga Khaka delivered a standout performance with the ball, finishing with 4 for 27, while Nonkululeko Mlaba supported well with 3 for 27. Their disciplined, stump-to-stump bowling restricted scoring opportunities and forced errors from the New Zealand middle order.
New Zealand captain Amelia Kerr admitted her side fell short in key moments: "We did not rotate strike well through the middle and could not find the boundaries when we needed them."
South Africa's fielding also proved sharp, highlighted by a direct-hit run-out from Annerie Dercksen and a clean take behind the stumps by Sinalo Jafta.
With the series now level, South Africa will take confidence from a well-rounded performance built on strong batting, disciplined bowling, and improved execution in key phases of the match.
